What to watch out for (particularly with diesel vessels)
Black exhaust smoke: could relate to overload of the engine, shortage of air or faulty worn injectors
White exhaust smoke: could mean injectors or valve timing is out, burning water in the engine, blocked cooling systems, cylinder head gaskets or leaking valves.
Blue exhaust smoke: could signal burning lube oil due to worn valves, stern seals or piston rings.
For fuel efficiency, we recommend antifouling and mechanical servicing to be conducted annually. At the same time, change the anodes, service and check everything such as legs, shafts and rudders, which will aid prevention of any future damage.
The lack of use of the vessel will be detrimental to the overall condition and reliability of any vessel, so make sure you make the time to get out there and enjoy it!
